HYDROCARB ON-B URNER.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed November 13,1907. Serial No. 402,009.

To all 'whom it may concern:

Be it known that I, WILLIAM SCRIMGEOUR, a citizen of the United States,residing at Portsmouth, in the county of Norfolk and IState of Virginia,have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to hydrocarbon burners, and the object of theinvention is to provide a burner capable of producing an intense fiume,while using comparatively low air-pressures. Y

In the preferred embodiment of the invention means are provided forcontrolling the flow of the portion of the air which is utilized foratomizing and distributing the hydrocarbon, thereby permitting a closeregulation and control of the flame.

For a full understanding of the invention reference is made to theaccompanying drawing wherein Figure 1 is a central vertical section of apreferred form of burner; Fig. 2 is a plan view of the saine; Fig. 3 isa transverse section on line 3 3 of Fig. 1 viewed in a forwarddirection; and Fig. ft is a transverse section on line 4-4, of Fig. 1viewed in a rearward direction.

In the drawings, 1 represents a burner cas-- ing having a flame-aperture2, the portion of the casing adjacent the aperture being preferablythickened as shown at 4 is the air-inlet end ofthe burner, provided withthe usual air-controlling means (not shown). I/Vithin the casing 1 andextending transversely across the same is a bridge 5, cast integral withthecasing and subdivi ding the same for the greater portion of itslength into upper and lower passages designated Gand 7 respectively. Thebridge 5 is preferably wedge-shaped, and the thicker or forward end 8terminates at a point approximately opposite the flame-aperture 2 andsomewhat in the rear of the same.

The top of the casing 1 is extended upwardly as indicated at 9, thesides of the enlargement converging upwardly as indicated in Fig. 4;.Within the space so provided is a wedge-shaped bridge member 10,integral with the burner casing, and serving to further subdivide theupper passage 6 into upper and lower passages 11, 12. Within thewedge-shaped member 10 is a transverse oilpassage 13, closed at one endby a removable plug 14k and fitted at the other end with a i,

serve to discharge the oil into the burner casing and toward the upperand forward portions of the walls of the enlargement 9 thereof. Theapertures 16 will vary in size and form in accordance with the characterof the oil and the pressure under which it is supplied. Above theoil-ports 16 and affording access thereto for cleaning I prefer toprovide a removable plug 17. As shown the lower face of this plug isformed with curved surfaces 18, 19 intersecting in a transverse edge orrib 20, the curved face 19 serving to direct the air downwardly and intoclose proximity to the ports 16. The forward portion of the enlargement9 termi nates in a downwardly projecting edge or rib 21, theconformation of parts being such that the coml'ningled air and oil oroil-vapor are thoroughly mixed, and are directed downwardly against theheated bridge 5. From this point they are conveyed by the air blastthrough the passage 6 to the forward end of the burner, are therecommingled with th air which has passed beneath the bridge, and aredischarged through the flame-aperture 2.

It is desirable, although not in all cases necessary, to provide meansfor controlling the quantity of air passing above the wedgemember 10 andinto proximity to the oilports 1.6. For this purpose I prefer toprovidea plug-valve 22, rotatably mounted in the casing above thewedge-member 10, and having an air-port 23; this plug-valve serves tocontrol the uppermost air-passage, or to entirely close the same, and isin operation regulated in accordance with the oil supply through theports 16, to secure a thorough distribution or atomizing of the oil.

By constructing the transverse member 10 in the form of a wedgepresenting its thin edge to the air-inlet and having its lower faceconverging toward the adjacent surface of the bridge 5, I am enabled tosecure important advantages in the more complete and rapid atomizationof liquid fuels. The form of air-passage 11 is such as to direct the airacross the mouth of the oil-port 16 and in large part to atomize the oilasit issues therefrom. The convergence of the passage 12 in thedirection of the air current results in a gradual increase in thevelocity of the air moving therethrough, and insures its delivery atmaximum velocity at a point where it commingles with the atomized oil;at the same time any oil iowlng in a film down the anterior ace or" themember l0 is intercepted and vaporized by the air at the moment ofemergence at relatively high velocity from the end of the passage 12.

he rearwardly tapering construction of the bridge S results in a similarprogressive increase in the velocity of the air moving through thepassage 7 and increases the effectiveness of the mixing action at itsdelivery end.

I claim:

l. A hydrocarbon burner comprising a casing having an air-inlet and avapor-outlet, and a wedge-shaped member extending across the casing andhaving its ledge directed toward the air-inlet, said wedgeshaped memberprovided with an oil-port.

2. A hydrocarbon burner comprising a casing having an air-inlet and avapor-outlet, a wedge-shaped member extending across the casing andhaving its edge directed toward the air-inlet, said wedgeshaped memberprovided with an oil-port, and a valve for controlling the air-passageabove said member.

3. A hydrocarbon burner comprising a casing having an air-inlet and avapor-outlet, a wedge-shaped member extending across the casing andhaving its edge directed toward the air-inlet, said wedgeshaped memberprovided with an oil-port, and a transverse bridge below saidwedgemember.

4. A hydrocarbon burner comprising a casing having an air-inlet and avapor-outlet, a wedge-shaped member extending across the casing andhaving its edge directed toward the air-inlet, said wedgeshaped memberprovided with an oil-port, and a transverse bridge below saidwedgemember and forming therewith an air-passage converging in thedirection of the aircurrent.

5. A hydrocarbon burner comprising a casing having an air-inlet and avapor-outlet, a wedgeshaped member extending across the casing andhaving its edge directed toward the air-inlet, said wedgeshaped memberprovided with an oil-port, and a rearwardly tapering transverse bridgebelow said wedge-member and forming therewith and with the bottom of thecasing air-passages converging in the direction of the air-current.

6. Av hydrocarbon burner comprising a casing having an air-inlet and aname-aperture at opposite ends, a substantially horizontal transversebridge or partition disposed between said air-inlet and Haine-apertureand terminating adjacent said flameaperture, said bridge tapering towardsaid air-inlet, and means for introducing oil above said bridge.

7. A hydrocarbon burner comprising a casing having an air-inlet and aflame-aperture at opposite ends, a transverse bridge or partitiondisposed between said air-inlet and name-aperture and terminatingadjacent said name-aperture, and a wedge-member disposed above saidbridge, said wedgemember having a transverse oil-passage and an upwardlyextending oil-port communieating therewith.

8. A hydrocarbon burner comprising a casing having an air-inlet and aname-aperture at opposite ends, a transverse bridge or partitiondisposed between said air-inlet and flame-aperture and terminatingadjacent said flame-aperture, a wedge-member disposed above said bridge,said wedge-member having a transverse oil-passage and an upwardlyextending oil-port communicating therewith, and controlling` means forthe air disposed above said wedge-member.

In testimony whereof, I afix my signature in presence of two witnesses.
